Description of problem: ltp->syscalls下ioctl_sg01用例执行fail，从2.23号开始失败，之后是大概率失败，偶尔执行成功，日志如下： Running tests....... <<<test_start>>> tag=ioctl_sg01 stime=1677550047 cmdline="ioctl_sg01" contacts="" analysis=exit <<<test_output>>> incrementing stop tst_test.c:1250: TINFO: Timeout per run is 0h 05m 00s tst_test.c:1250: TINFO: Timeout per run is 0h 15m 00s ioctl_sg01.c:83: TINFO: Found SCSI device /dev/sg0 tst_test.c:1295: TINFO: If you are running on slow machine, try exporting LTP_TIMEOUT_MUL > 1 tst_test.c:1296: TBROK: Test killed!
